Letters Patent No. 85,008, dated December 15, 1 868.

IMPROVED CARRIAGE-SPRING.

To all whom it may comm Be it known that I, FRANK A. Hunrnve'ron', of the city and county of 'San. Francisco, State of California, have invented an Improved Oan'iage-Sprmg; and I do hereby declare the following description and accompanying drawings are suflicient to enable any person skilled in the art or science to which it most nearly appertains, to make and use my said-invention orimprovements without further invention or experiment. The object of my invention is to provide an improved carriage-spring, so constructed that a weight placed on any part of the carriage will depress the springs on each side equally, creatin If no unduestrain on any portion, and so arranged an applied as to impart to the carriage the greatest elasticity, without'impairing'its strength; and

It consists in employing separate springs or levers for each end of the carriage, one end of which is pivoted to a clip, which is attached to the centre of the body on each side, the -opposite ends being secured by shackles to curved pieces of metal attached to the b0l= ster and axle-bed; A bar sses from the levep on one side to the lever on the o t fier, a short distancefrom and on each side of the clip-connection, and springs or bumpers, made of India rubber or other'elastic material, are placed at each end of the cross-bars, upon which the body rests.

Tomore fully illustrate and describe my invention, reference is had to the accompanying drawings, and letters marked'thereon, of which Fi" ure 1 is a side view.

Fi e 2 is a plan.

Figure 3 is an end view.

A is the body-rail of a buggy, around the centre of which the clip B passes. Straight bars or levers O 0, made of wood or metal, have their ends pivoted to this clip, the opposite end being secured, by shackles D D, to'the end of curved metal bars E E, attached to the ends of the reaches, over the bolster and axle-bed, thus forming two levers on each side, having theirfulcrum at the point of attachment to the body of the carriage. Bars F F pass across fi'om one spring to the other, having their ends resting on the levers at each side, a short distance fi-om the' -clip-atta'chment.

, Springs or bumpers G G, made of India rubberor other elastic material, are secured to the ends of the bars, F F, and are so placed that they receive the weight placed in the carriage. -The levers being so attached at each end, that they will give until brought up by the bodycompressing therubber springs, there can be no unequal strain upon any part, no difierence' in what part of the buggy the weight maybe placed.

By this construction, a light, easy, and durable buggyv or carriage may be'made, cheap and simple in-construction, and neat inappearance;

Having thus described my invention, What I claim, and desire to secureby Letters Pat cut is-- f Clihe rigid levers O O and springs G G, in combination with the adjustable bars F F, the whole arranged substantially in the manner and for the purposes described. Y

In witness whereof, I have hereunto set my hand and seal.
